RFA SS ATHELSTANE

British Royal Fleet Auxiliary (RFA) Tanker

Historical Overview

The SS Athelstane was a British Royal Fleet Auxiliary (RFA) tanker constructed in 1918. As a vital logistical support vessel, she was essential for maintaining the operational capacity of the British fleet in the Indian Ocean. She was under escort by the corvette HMS Hollyhock when both ships came under attack during the massive Japanese air raids on Ceylon in April 1942.

The vessel was struck by Japanese bombs. A direct hit on one of her central fuel tanks caused significant damage and ignited a fire. Remarkably, despite the heavy damage the ship remained afloat for over two hours. This delay allowed all crew members on board to survive making it a rare loss without fatalities.

Diving Experience

The wreck is spread across a gentle seabed slope, resting in three distinct, relatively well preserved sections. The hull rests across a gradient, with the bow at 120 feet and the stern at 140 feet.

Retains two intact anchors and a clearly visible bow winch. Access for penetration into inner compartments is possible. Unusually for a wreck of this age, the ship's bridge remains standing upright despite damage from the explosion.

Stern section, features one large propeller blade and the rudder still attached. A visible stern mounted deck gun remains intact, confirming the ship's armed support role during wartime operations.

Depth is 120 to 140 ft and wreck is suitable for Technical Deep Diving. visibility can vary (10-20 m) and currents can be present. The bottom is sandy with reef growth and scattered debris.
